Scientists discover how a single cell builds a brain with 170 billion cells

Scientists have uncovered a groundbreaking method on how a single cell can orchestrate the development of a brain comprising 170 billion cells. They found that brain cells use their lineage, or cellular family tree, to maintain organization. This means cells from the same ancestor stay together, aiding in brain self-organization rather than depending entirely on chemical signals. This discovery sheds light on fundamental brain development processes and could have significant implications for understanding neurological disorders and advancing brain-related research.
